High Purity System

Pipes/Tubes for Semiconductor Production

▶ AP (Annealing and Pickling)
– Most common final process for stainless steel production, by which internal stress and oxidized substances remove.

▶ MP (Mechanical Polished Finish)
– After AP process, the surfaces get ground by sandpapers.

▶ BA (Bright Annealed Finish)
– One of final processes, by which steel stress removes and no oxidized substances remains. No pickling required.

▶ EP (Electro Polished Finish)
– After doing either BA or MP, very high bright surfaces are acquired through EP.
